Since the discovery of a Higgs-like boson by the ATLAS and CMS experiments at the LHC, the emphasis has shifted towards measurements of its properties in order to determine whether the new particle is the Standard Model (SM) Higgs boson, or something else. Of particular importance is the direct observation of the coupling of the Higgs boson to fermions. In this presentation a comprehensive...

A review of the latest results of individual diboson channels measurements of the Higgs boson main properties, with the ATLAS detector using approximately 25 fb-1 of pp collision data collected at 7 TeV and 8 TeV in 2011 and 2012, is given.
The measurements discussed are the mass, couplings, spin and parity, in the diphoton, WW (lvlv) and ZZ (llll) channels through various production...

WW scattering is dominated at high energies by their longitudinal components, which are the most sensitive to the nature of the electroweak symmetry breaking. Prior to the discovery at the LHC of a Higgs-like particle, unitarization tools were extensively used to show that, in the absence of a light Higgs boson, new resonances resulting from the would-be strongly interacting electroweak sector...

The Higgs-like boson discovered by the ATLAS and CMS collaborations is a
candidate for the last unobserved particle predicted by the Standard Model (SM). The next experimental step is the measurement of its properties, most notably its couplings. This contribution will present the searches for the SM Higgs boson via decays in rare modes such as dimuon pairs, decays to Z gamma or invisible decays.

The discovery of a Higgs-like boson with a mass of about 125 GeV has prompted the
question of whether or not this particle is part of a much larger and more
complex Higgs sector than that envisioned in the Standard Model. In this talk,
we outline the current results from the ATLAS Experiment regarding Beyond the
Standard Model (BSM) Higgs hypothesis tests. Searches for additional Higgs...

New light bosons with typically weak coupling to standard model (SM) particles are predicted in several extensions of SM. Examples of the relevant scenarios are supersymmetric models with hidden valleys (dark SUSY) or models with extended Higgs sector (NMSSM). In these extensions of SM, the new bosons may be produced either promptly or via a SUSY decay chain. Depending on the branching ratio,...

Working in the framework of effective Lagrangians with the SU(2)_L x U(1)_Y symmetry linearly realized, we analyze the constraints on Higgs couplings to the standard model gauge bosons using the available data from Tevatron and LHC. Moreover,
modifications of the couplings of the Higgs field to the electroweak gauge bosons are related to anomalous triple gauge couplings (TGC). We also show...

This talk will discuss recent attempts to improve Higgs search
analyses at the LHC using a class of correlated observables known as Fox-Wolfram moments. A comparison of the main Standard Model Higgs production mechanisms of gluon fusion and vector boson fusion to common backgrounds is performed using the moments. We show that the moments are, at first glance, at least as good as current...
